'7 Claims.

This invention relates to improvements in vending machines, and one of the objects of the same is to provide in a machine of this character improved means whereby a plurality of differently priced articles or commodities, may be selectively vended by means of an actuator which is common to all of the ejecting mechanism of the separate supplies, and which actuator may be selectively rendered active with respect to the ejector for the supplies, by the insertion into the proper receiving'opening in themachine the proper check, coin or token.

A further object is to provide improved means forpreventing the actuation of the ejectors by the insertion of an improper coin or token.

' A further object is to provide improved means for preventing the ejecting machine from' being actuated when the respective supply of articles is exhausted.

A further object is to provide an improved ma chine of this character which will be comparatively simple and compact'in construction and effective and efficient in operation. j

To the attainment ofthese ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty inosubstantially the construction, combination and arrangement of the several parts, hereinafter more fully described'and claimed and shown in the accompanying drawings,'illustrating this invention and in which,

I

'The machine consists essentially of a casing having an upper portion IE3, in which there is arranged a plurality of chutes or supply holders i5 for containing the commodity Hi. In the present form of the invention four columns or supply holders are disclosed, but it is to be understoodany number of such supply holders may be provided, and each is provided with its own eject ing mechanism. All of the ejecting mechanisms are responsive to the operation of a common actuator ll, which latter is arranged in a convenient position for the" operator, and as the construction and operation of each of the ejecting mechanisms is the same, the description of one will apply equally as well to them all.

The base [.8 of the casing is enlarged, and the ejecting mechanisms are arranged within the base, the ejector for respectivecolumns or supply holders being' disposed adjacent the same and of the casing, and extends transversely of all' o'f the supplies. Connected to the shaft 2|, as at 22, is one end of a spring 23, preferably a coil spring, the other end of the spring being anchored as at 24, and the spring tends normally to rotate the shaft 2| in one direction.

The shaft 2! is rotated in the opposite direction and against the stress of the spring 23 by means of the actuator ll, the latter preferably being in the form of an upright member movable through a shelf or ledge 25 formed between the base l8 and the upper portion H: of the casing, and also moves through aguide 26 to project into the base of the machine. i 4

The numeral 21 designates a lever which is pivotally mounted as at 28 to a fixed stationary support. The other end 29 of the lever is connected to the lower end of the actuator H, in

any suitable manner, but preferably by projecting into an opening or bifurcation 38 in the end of the actuator, as shown more clearly in Figure 2, and the end 29 of the lever 21 may be rounded, if desired, to facilitate operation.

Secured to the shaft 2| in any suitable manner, preferably by shaping the extremity of the shaft so as to be irregular in cross section, is a disk 3|, which is provided with an openingconforming in contour with, and receiving the angular extremity of the shaft 2|.

The lever 27 is connected to the disk 3|, preferably by means of a link 32, one end of which is pivotally connected as at33 to the lever, and the other end is pivotally connected as at 34 to the disk 3|. A portion of the periphery of the disk 3| is cut away as at 35 to form stops 35, 31, to engage an abutment 38, which latter preferably projects into the cut away portion 35 of the disk, to limit the movements'of the disk 3|, as well as the rotation of the shaft 2|, under the operation of the actuator H or the spring 23.

Portions of the periphery of the disk 3| are also cut away as at 39, 43, and these cut away portions are spaced from each other in directions about the periphery, to form a portion 4| therebetween, and this portion 4| is provided with teeth 42 with which latter a spring controlled pawl 43 cooperates. The pawl 43 with the teeth 42 serve the purpose of necessitating the movement of the disk 3| for a predetermined distance in one direction, before the disk can be rotated in the opposite direction, that is, with the parts shown in Figure 2, when the actuator I1 is depressed, the disk 34 will be rotated in the direction of the arrow, causing the spring pawl 43 to ride over the teeth 42. This will place the spring 23 under tension. Before the shaft 2| and disk 3| can be rotated in the opposite direction under the stress of the spring, the disk 3| must be moved by the actuator to the full extent of its movement in the same direction, or until the pawl 43 passes off of the teeth 42 and enters the recess'or cut away portion 39.

Similarly, when the disk 3| is rotated in the opposite direction, the pawl 43 must pass on of the teeth 42 and project into the opening or recess 40 in the disk before the direction of movement of the disk can be reversed.

, Carried by the shaft 2| are a plurality of check carriers designated generally by the reference numeral 44 (see Fig. 10), one adjacent each of the coin chutes 45, one coin chute being provided for each of the supply holders l5 The coin chute 45 opens through the front portion of the casing as at 46, and inclines downwardly so that, under certain conditions, when a coin is deposited into the chute 45, it will drop from the chute into a pocket or holder 47 in the coin carrier 44.

The coin carrier 44 is also provided with another pocket or seat 48 which opens through the front of the carrier as at 49, and extending from one of the walls of the seat 48 is a projection 59, and a portion of the wall between the pockets 4'! and 48 is cut away as at 5|, see particularly Fig. 10, so as to permit the coin to pass from the pocket or seat 41 into the pocket or seat 48.

In a wall 52 adjacent the discharge opening 49 of the pocket 48 is a slot 53, through which the coin or token which is depositedin the pocket or seat 48 will be discharged whenthe shaft'2l and the check carrier 44 are rotated in the proper direction to cause such discharge. The check being delivered through the opening 53 will be returned to the operator through an opening 54 in the front wall of the base of the casing, and through which opening the articles to be vended are also delivered to the operator.

The seat 47 of the check carrier is disposed in a plane in alinement with the outlet end of the coin discharge chute 45, so that when a coin, as above stated, is deposited in the chute 45 it will, under certain conditions, drop into the seat or pocket 41, and will be carried back into the machine, during which time it sets other mechanism in motion to discharge or vend an article, as will be'described.

However, under certain other conditions, when the check carrier 44 is operated upon the deposit of a coin or check in the chute 45, the coin will not drop into the pocket 41, but will be held in position and within the mechanism until the lateral projection 53 assumes a position beneath the coin, and the coin will drop onto the projection 50 and will be directed into the pocket or seat 48 to be discharged through the opening 53 and returned to the operator. This latter operation will happen when the supply of articles is exhausted, in a manner to be hereinafter described.

The numeral 55 designates a stationary shaft which is arranged parallel to the shaft 2| and carried thereby and oscillatabie thereupon is a sleeve 55 (see particularly Figure 8) and to which sleeve is connected an arm 56, which in turn is connected with an ejector or slide 51 by means of a link 58. The ejector or slide 51 is guided in its movement by means of depending lugs or projections 59, which reciprocate in a slot 69 in a supporting platform 5| within the base of the machine. A spring 52 is anchored by one end as at 63, to the arm 56 and at 64 to a fixed support, and the spring tends normally to retract the slide or ejector 51 as well as to move the shaft 55 in one direction.

Connected also to the sleeve 55 for oscillation therewith, is a member 65 provided with a cam portion 65 and an arm 5?. This member 65 is so positioned that the arm 61 will, when the check carrier 44 is moved in one direction, enter and move within the space or pocket 41 of the check carrier 45, the portion 66 moving against a wall 68 forming a part of the coin chute within the base of the machine.

When the parts are in the position shown in Figure 3, and a coin is delivered into the seat 41, and when the check carrier is moved in the direction indicated by the arrow as indicated in Figure 3 as well as in Figure .6, the check 69 will be moved by the check carrier in the same direction, that is as shown in Figure 5, to the position shown in Figured The coin or check 69 will engage the arm 67 and rock the sleeve 55 and with it the arm 55, thereby moving the ejector or slide 51 from the position shown in Figure 5 to the position shown in Figure 6, so that the front end of the ejector or slidewill contact the lowermost article IS in the supply I5 and discharge the same from the support 6| so that it will be delivered to the operator through the vending oulet 54.

These movements of the parts will place the springs 23 and 62 under tension, so that when the check 69 is discharged from the seat 4! into the machine as indicated by the arrow in Figure 6, and the actuator I! is released, the slide 51 with its associated parts, and the shaft 2| and check carrier 44, will be returned to their normal positions.

The wall 68 forms a part of the check chute and when the check 69 is deliveredfrom the chute 45, itwill engage an abutment 69 (see Figures 3- and 5) and drop upon the end ll] of a pivotally mounted member H, and which memher is preferably in the form of a wire, that has a portion I2 thereof bent upwardly to project through a suitable opening #3 in the support 6i and into the supply holder [5 This member 1 I is pivoted in suitablebearings T l (see particu r the weight thereof will depress the portion '62 of the member H and move the latter about its pivot 14 to lower the end it and thereby allow the check to drop into the seat of the check carrier 44." 5 1 1 When, however, the supply I5 is exhausted, the spring 15 will move the portion 12 of the member I! upwardly above the support iii, and

hold it in such position and move the end is into the position shown in Figure 3. This will prevent the check from dropping into the seat ll, but will retain the check in the chute and against delivery to the check carrier 44, so that it may be returned'to the operator, in a manner which will be presently described.

The detector mechanism consists of a member 16 which is mounted to swing about an upright pivot Tl, moved in one direction by means of a spring I8, and-which carriesa magnet [9 arranged adjacent an opening in the member l5. The magnet 19, as well as the opening 8t, is disposed adjacent the end 8! of the coin chute 45,. and in proximity to the point where the coin will fall from the chute 45 to drop upon the end 10 of themember H, in proximity to an opening 82 in the wall 68.

Carried by the member '56 is an arm 83, a por tion of which latteris spaced from the member 16 and is provided with a laterally deflec ed portion 84 in proximity to the opening 86, and serves as a means to form a portion of the chute,-to direct and hold the coin to its seat upon the end 10 of the member H, a portion of the wall 68 cooperating with the member'lfi to hold the coin in position.

Carried by the wall 68 is a stationary bracket or arm 85 that has a portion 85 disposed adjacent the opening 80, and which portion to is opposed to and spaced from the portion 84 of the bracket 83, so that when the member it isswung about its pivot 11, the portion 34 of the bracket 83 will be movedthrough the opening 82in the wall-68, while the portion86 of the stationary bracket or member 85 will project betweenthe legs of the' magnet 19 that is moved thereover, and through the opening 89 in the member '06 to strip from the magnet any slug or token that may be attracted to and held by themagnet.

When a slug which is subject to magnet action is inserted into the checkchute45, it will beattracted by the magnet just as itfalls from the chute at 8!, see Fig. 4,'and subsequently, and in a manner to be later described, the member'lti will be swung about its pivot l'land will'carry such slug out of alinement with the pocket or seat 41 in the check carrier Aid, to a-posi'fion over the seat or pocket 48 in the'check carrier.

Just as the check moves to this position, the portion 86 of thestatiOnary bracket, 85 will act as a stripper, and' will strip the slug from the pocket ll,

magnet, allowing it to drop into the pocket or seat 38 of the check carrier 44, so that when the actuator His released, and the check carrier M moves under the stress of the'spring 23 to the position shown in Fig. 3, the slug will be delivered through the opening 53 in the casing wall back to the operator. 7 i

The arm 83 also acts as a stop to limit the swinging movement .of the member 16 in one direction, by engaging the wall 68. Likewise when the member i6 is moved under the stress of the spring Hi to return the member 16 and the magnet "is to normal position, the wall 68 will be engaged by the member l6, and the movement of the latter in that direction will be arrested.

Any suitable means may be provided for swinging the member 'i'i about'its pivot H against the stress of the spring l8. Y A simple and efficient means embodies a cam til, see particularly Figures 3, 8 and 10, which is carried by the check carrier M, and cooperates with'an arm or finger 88 carried by the member ME.

' When the check carrier is moved from the position shown in Figure 3 to the position shown its normal position shown in Figure 3, the various other springs will return the respective parts to their normal positions.

An upright 39 is provided adjacent'the end of the chute to assist in directing and posi tioning' the coin 59 upon the end is of the member H and also for directing the coininto the This upright is positioned'so that it extends into the pocket 4W and as the check carrier is oscillated, the upright til-will move in the pocket, the upright being stationary.

, When a coin, in the absence of any commodity in the supply holder mam a slug under any condition, is deposited in the pocket the finger or laterally projecting portion 553 on the check carrier will also serve as a means for carrying the same forwardly with the check carrier to discharge the contents of the pocket is in the check carrier through the opening 53 baclc to the operator.

When the supply holder Eli is exhausted, the weight is will assume a position that the open portion at the bottom thereof willbe disposed above the portion T2 of the member "it, so that the portion E2 will enter such opening, as shown in Figure 12, to prevent the coin from being deposited into the machine, but the coin will be returned to the operator when the parts are in the position shown in Figure 3.

r A The bottom of the check chute 25 is preferably of'a V-shape formation to provide a narrow groove 98, so that coins of different thicknesses may travel in. different planes affording a means Figures J. and 4 with the open side @lbelow the other side of the chute.

With this construction and when a slug or a proper check is inserted into the check chute through the opening 46, it Will be delivered into the machine, but when a token of smaller diameter than the diameter of the token necessary to operate the machine, or a very thin slug or token is inserted in the chute, the position or inclination of the chute will cause such slug to tilt laterally as it passes through the chute, and will fall out of the open side 9| before it reaches the operating mechanism and before it has traveled to any great extent in the chute. Similarly, a very thin slug will enter the bottom of the groove 98, and it will fall over sidewise and drop out of the machine before it passes into the operating mechanism.

It is thought that the operation of the machine will be clearly understood from the foregoing, but briefly stated, it is as follows:

In Fig. 3 the parts are represented in their normal position and the supply holder I5 is empty.

When a proper coin is then delivered into the coin chute 45 it will drop out of the end of the chute upon the end 10 of the member just in advance of the edge of the stationary upright 89, and will be held in such position until the actuator I! is depressed to rock the coin carrier.

Upon depressing the actuator H, the coin will be thus held until the projection 50 on the carrier passes beneath the coin. Just at that time the cam 81 engaging the arm 88 will begin to swing the wall or element 16 about its pivot against the stress of the spring 18. As the coin carrier is being further moved in the direction of the arrow in Figure 3, the cut away portion 5| in the wall between the pockets or receivers 41.49, will be moving to a position in close proximity to the coin. Just at this time the projection 50 will be passing under the coin. The portion of the member 16 adjacent the end 18 of the member 7|, which forms a part of the coin chute, will then be moving laterally by the action of the cam 81 on the arm 88, and the coin will fall through the cut away portion 5| into the check seat or receiver 48, to be delivered out of the machine and back to the customer.

When, however, the holder |5 contains a supply of articles, the portion 72 of the member II will be depressed so as to move the end 18 thereof out of the way, as shown in full lines in'Figure 5, to allow the proper coin or check to drop into the check seat 4? in advanceof the upright 89. When the actuator I1 is then depressed, the shaft 2| will be rotated to move the check carrier in the direction indicated by the arrows in Figures 3, 5 and 6. This will cause the coin 69 to engage the arm 61 of the member 65 and rock the sleeve 55 to actuate the ejector 51, as shown in Figure 6.

After the commodity has been delivered, the parts will be returned to their normal positions under the stress of the respective springs.

Should a magnetically influenced slug or iron token be inserted in the check chute, it will, when it drops from the end 8| of the chute, be attracted by the magnet 19 to be held thereby, and, as the check carrier 44 is then moved in the direction of the arrows, the cam 81 engaging the arm 88 of the detector mechanism, will swing the member 16 about its pivot 11 carrying such magnetic slug with it, until the slug contacts the stationary stripper 86 (see Figure 4) and a further movement of these parts in the same direction will cause the slug to be disengaged from the magnet. At this point in the operatiomthe magnet will have carried the slugto a position directly over the pocket or seat 48 in the check carrier, so that upon return of the check carrier to its normal position, and with the fallen or ejected slug in the seat 48, the slug will be delivered through the opening 56 back to the operator.

In the event that the holder l5 is empty, and a proper coin 69 (see Figure 3) is delivered into the coin chute 45, the coin will fall upon the end 10 of the member 7| in advance of the upright 89 and at the side of the adjacent portion of the member 16 to be held temporarily in this position until the cam 81 on the coin carrier engaging the arm 88, moves the member 16 about its pivot 11, allowing the coin to drop through the cut away portion 5| in the check carrier into the check seat 48 to be delivered back to the operator.

Inasmuch as a portion of the member 16 assists in holding the coin upon the end 10 of the member 1| (see Fig. 3), the coin will, as soon as the member 7| is moved about its pivot by the cam 81, drop off of the end 10 of the member H and will engage and be deflected by the finger or projection 58 on the check carrier, into the pocket 48, to be discharged on return of the check carrier through the opening 53 back to the operator, as shown in dotted lines in Figure 3.

Should the supply holder I5 be empty, the weight l8 (see Figure 12) will drop down and assume a position, to permit the portion 12 of the member H to enter the opening 28 in the bottom of the weight, and the coin will be returned to the operator and the ejecting mechanism will be maintained against operation. 7

If a thin slug, or a small diameter slug, is inserted in the check'chute, the construction and angles of'inclination of the chute will cause it to fall out of the chute through the open side 9| thereof, before it can be delivered into the machine.

It will thus be seen that with the present invention there is provided a machine in which a plurality of differently priced articles may be selectively vended through the medium of a single actuator, which is common to all of the supplies of articles. Each supply, however, has its own coin control mechanism, and the mechanism for the respective supplies is such that the proper or necessary check or coin must be employed before the articles can be vended from such supply. Furthermore, when the machine is operated to vend one of the articles, it cannot be again operated until the parts are returned to normal position and another proper check inserted.

With this improved machine, it also is possible to simultaneously vend a plurality of articles, by inserting the proper check or token in the proper coin receiving openings of the respective supplies, so that upon operation of the actuator all of the mechanisms which have been supplied proper checks or tokens will be simultaneously actuated. It is also impossible to operate the machine with a coin or token which is of a smaller diameter than the required check, or which may be thinner than the required check, or by any magnetically influenced slug which is inserted in the machine, and any slug or token, other than the proper token, which may be inserted into the machine will be delivered back to the operator. The proper token, although inserted into the machine, will be returned to the operator when the particular supply is exhausted.

By the use of the term proper check is meant a check of the proper size, shape, etc., that when inserted the desired actuation of the mechanism may be produced, while by the use of the term improper check is meant a check which does not possess the proper characteristics as to produce the desired or proper action of the mechanism to vend or dispense the article upon the operation of the actuator l1.

While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

Furthermore, while in the present exemplification of the invention, four supplies with their respective ejecting mechanisms have been shown, it is to be understood that any number of supplies may be provided, in a similar manner, to be actuated by a single actuator.
